Optimal control method of active distribution network considering soft open point and thermostatically controlled loads under distributed photovoltaic access

To achieve the flexible operation of active distribution network (ADN), an optimal control method for ADN considering soft open point (SOP) and thermostatically controlled loads under distributed photovoltaic (PV) access is proposed. First, mathematical model SOP are constructed based on flexibility thermal storage characteristic loads, respectively. Then, further constructed. The realized by adjusting transmission power switching state electric water heater. Finally, analysis various methods carried out, impact economic secure investigated. results show that proposed taps demand response potential while satisfying consumption habits different customers, utilizes reconfiguration with to improve security economy operation.
